He has been accused in Turkish media reports of having ties to Fethullah Gulen, a U.S.-based cleric the Turkish government accuses of masterminding the coup. Gulen, a former ally-turned-critic of Turkish President Recep Tayyip Erdogan, has denied any involvement.

Another Turkish Canadian, Ilhan Erdem, was also arrested last month at Istanbul’s Ataturk Airport.

Since a state of emergency was declared in the failed coup’s aftermath, some 35,000 people have been detained for questioning. More than 17,000 of them — including soldiers, police, judges and journalists — have been formally arrested to face trial.

McCallum, in Calgary for a roundtable on immigration, said it is difficult to comment on an individual case because of privacy concerns.

Hanci’s wife, Rumeysa, said in an interview this week that she hasn’t been able to get an explanation from Turkish authorities about what her husband is accused of doing.

She said she has trust in the Canadian government.

“I have a lot of faith in the Canadian government. They can do their best in their power to bring my husband home safely,” she said.

“The only thing I want is my husband back.”

McCallum said speaking publicly about the Hanci case isn’t worth the risk.

“It’s best not to discuss elements of an individual case in public,” McCallum said.

“It could do harm. It could do good. It’s better to work behind the scenes on such cases to see what we can do without getting too much into the media on individual cases.”
